Gu Wan is a contract employee with a college diploma at Lanzhou Life Insurance. For eight consecutive years, she has ranked first in sales, bringing in 15 billion yuan in insurance premiums on her own and supporting two-thirds of the company's business. Yet her monthly salary is only 3,000 yuan. All five opportunities for permanent positions have been secretly given by Vice President Gao Hua to his niece, Zhao Siqi. Unable to tolerate the injustice any longer, Gu Wan begins negotiating a move to Hengxin Life Insurance with He Ming, and a large number of her clients follow her. At the company's annual meeting, the corruption is exposed, triggering a wave of policy cancellations and a liquidity crisis at Lanzhou Life Insurance. After Gu Wan changes companies, Gao Hua and Zhao Siqi repeatedly try to sabotage her, but she overcomes every obstacle. By chance, Gu Wan discovers that two major clients, father and son Zhou Zhenhai and Zhou Heng, are the very people she once saved. In the end, all the villains are brought to justice, and Lanzhou Life Insurance goes bankrupt.
